BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates in general to the field of computers andsimilar technologies, and in particular to software utilized in thisfield. Still more particularly, it relates to a method, system andcomputer-usable medium for performing cognitive inference and learningoperations.

Description of the Related Art

In general, “big data” refers to a collection of datasets so large andcomplex that they become difficult to process using typical databasemanagement tools and traditional data processing approaches. Thesedatasets can originate from a wide variety of sources, includingcomputer systems, mobile devices, credit card transactions, televisionbroadcasts, and medical equipment, as well as infrastructures associatedwith cities, sensor-equipped buildings and factories, and transportationsystems. Challenges commonly associated with big data, which may be acombination of structured, unstructured, and semi-structured data,include its capture, curation, storage, search, sharing, analysis andvisualization. In combination, these challenges make it difficult toefficiently process large quantities of data within tolerable timeintervals.

Nonetheless, big data analytics hold the promise of extracting insightsby uncovering difficult-to-discover patterns and connections, as well asproviding assistance in making complex decisions by analyzing differentand potentially conflicting options. As such, individuals andorganizations alike can be provided new opportunities to innovate,compete, and capture value.

One aspect of big data is “dark data,” which generally refers to datathat is either not collected, neglected, or underutilized. Examples ofdata that is not currently being collected includes location data priorto the emergence of companies such as Foursquare or social data prior tothe advent companies such as Facebook. An example of data that is beingcollected, but is difficult to access at the right time and place,includes data associated with the side effects of certain spider biteswhile on a camping trip. As another example, data that is collected andavailable, but has not yet been productized of fully utilized, mayinclude disease insights from population-wide healthcare records andsocial media feeds. As a result, a case can be made that dark data mayin fact be of higher value than big data in general, especially as itcan likely provide actionable insights when it is combined withreadily-available data.

The computerreadable program instructions may execute entirely on the user'scomputer, partly on the user's computer, as a stand-alone softwarepackage, partly on the user's computer and partly on a remote computeror entirely on the remote computer or server. In the latter scenario,the remote computer may be connected to the user's computer through anytype of network, including a local area network (LAN) or a wide areanetwork (WAN), or the connection may be made to an external computer(for example, through the Internet using an Internet Service Provider).In some embodiments, electronic circuitry including, for example,programmable logic circuitry, field-programmable gate arrays (FPGA), orprogrammable logic arrays (PLA) may execute the computer readableprogram instructions by utilizing state information of the computerreadable program instructions to personalize the electronic circuitry,in order to perform aspects of the present invention.

Aspects of the present invention are described herein with reference toflowchart illustrations and/or block diagrams of methods, apparatus(systems), and computer program products according to embodiments of theinvention. It will be understood that each block of the flowchartillustrations and/or block diagrams, and combinations of blocks in theflowchart illustrations and/or block diagrams, can be implemented bycomputer readable program instructions.

These computer readable program instructions may be provided to aprocessor of a general purpose computer, special purpose computer, orother programmable data processing apparatus to produce a machine, suchthat the instructions, which execute via the processor of the computeror other programmable data processing apparatus, create means forimplementing the functions/acts specified in the flowchart and/or blockdiagram block or blocks.

The flowchart and block diagrams in the Figures illustrate thearchitecture, functionality, and operation of possible implementationsof systems, methods, and computer program products according to variousembodiments of the present invention. In this regard, each block in theflowchart or block diagrams may represent a module, segment, or portionof instructions, which comprises one or more executable instructions forimplementing the specified logical function(s). In some alternativeimplementations, the functions noted in the block may occur out of theorder noted in the figures. For example, two blocks shown in successionmay, in fact, be executed substantially concurrently, or the blocks maysometimes be executed in the reverse order, depending upon thefunctionality involved. It will also be noted that each block of theblock diagrams and/or flowchart illustration, and combinations of blocksin the block diagrams and/or flowchart illustration, can be implementedby special purpose hardware-based systems that perform the specifiedfunctions or acts or carry out combinations of special purpose hardwareand computer instructions.

FIG. 1 is a generalized illustration of an information processing system100 that can be used to implement the system and method of the presentinvention. The information processing system 100 includes a processor(e.g., central processor unit or “CPU”) 102, input/output (I/O) devices104, such as a display, a keyboard, a mouse, and associated controllers,a hard drive or disk storage 106, and various other subsystems 108. Invarious embodiments, the information processing system 100 also includesnetwork port 110 operable to connect to a network 140, which is likewiseaccessible by a service provider server 142. The information processingsystem 100 likewise includes system memory 112, which is interconnectedto the foregoing via one or more buses 114. System memory 112 furthercomprises operating system (OS) 116 and in various embodiments may alsocomprise cognitive inference and learning system (CILS) 118. In theseand other embodiments, the CILS 118 may likewise comprise inventionmodules 120. In one embodiment, the information processing system 100 isable to download the CILS 118 from the service provider server 142. Inanother embodiment, the CILS 118 is provided as a service from theservice provider server 142.

In various embodiments, the CILS 118 is implemented to perform variouscognitive computing operations described in greater detail herein. Asused herein, cognitive computing broadly refers to a class of computinginvolving self-learning systems that use techniques such as spatialnavigation, machine vision, and pattern recognition to increasinglymimic the way the human brain works. To be more specific, earlierapproaches to computing typically solved problems by executing a set ofinstructions codified within software. In contrast, cognitive computingapproaches are data-driven, sense-making, insight-extracting,problem-solving systems that have more in common with the structure ofthe human brain than with the architecture of contemporary,instruction-driven computers.

To further differentiate these distinctions, traditional computers mustfirst be programmed by humans to perform specific tasks, while cognitivesystems learn from their interactions with data and humans alike, and ina sense, program themselves to perform new tasks. To summarize thedifference between the two, traditional computers are designed tocalculate rapidly. Cognitive systems are designed to quickly drawinferences from data and gain new knowledge.

Cognitive systems achieve these abilities by combining various aspectsof artificial intelligence, natural language processing, dynamiclearning, and hypothesis generation to render vast quantities ofintelligible data to assist humans in making better decisions. As such,cognitive systems can be characterized as having the ability to interactnaturally with people to extend what either humans, or machines, coulddo on their own. Furthermore, they are typically able to process naturallanguage, multi-structured data, and experience much in the same way ashumans. Moreover, they are also typically able to learn a knowledgedomain based upon the best available data and get better, and moreimmersive, over time.

It will be appreciated that more data is currently being produced everyday than was recently produced by human beings from the beginning ofrecorded time. Deep within this ever-growing mass of data is a class ofdata known as “dark data,” which includes neglected information, ambientsignals, and insights that can assist organizations and individuals inaugmenting their intelligence and deliver actionable insights throughthe implementation of cognitive applications. As used herein, cognitiveapplications, or “cognitive apps,” broadly refer to cloud-based, bigdata interpretive applications that learn from user engagement and datainteractions. Such cognitive applications extract patterns and insightsfrom dark data sources that are currently almost completely opaque.Examples of such dark data include disease insights from population-widehealthcare records and social media feeds, or from new sources ofinformation, such as sensors monitoring pollution in delicate marineenvironments.

Over time, it is anticipated that cognitive applications willfundamentally change the ways in which many organizations operate asthey invert current issues associated with data volume and variety toenable a smart, interactive data supply chain. Ultimately, cognitiveapplications hold the promise of receiving a user query and immediatelyproviding a data-driven answer from a masked data supply chain inresponse. As they evolve, it is likewise anticipated that cognitiveapplications may enable a new class of “sixth sense” applications thatintelligently detect and learn from relevant data and events to offerinsights, predictions and advice rather than wait for commands. Just asweb and mobile applications changed the way people access data,cognitive applications may change the way people listen to, and becomeempowered by, multi-structured data such as emails, social media feeds,doctors notes, transaction records, and call logs.

However, the evolution of such cognitive applications has associatedchallenges, such as how to detect events, ideas, images, and othercontent that may be of interest. For example, assuming that the role andpreferences of a given user are known, how is the most relevantinformation discovered, prioritized, and summarized from large streamsof multi-structured data such as news feeds, blogs, social media,structured data, and various knowledge bases? To further the example,what can a healthcare executive be told about their competitor's marketshare? Other challenges include the creation of acontextually-appropriate visual summary of responses to questions orqueries.

FIG. 2 is a simplified block diagram of a cognitive inference andlearning system (CILS) implemented in accordance with an embodiment ofthe invention. In various embodiments, the CILS 118 is implemented toincorporate a variety of processes, including semantic analysis 202,goal optimization 204, collaborative filtering 206, common sensereasoning 208, natural language processing 210, summarization 212,temporal/spatial reasoning 214, and entity resolution 216 to generatecognitive insights.

As used herein, semantic analysis 202 broadly refers to performingvarious analysis operations to achieve a semantic level of understandingabout language by relating syntactic structures. In various embodiments,various syntactic structures are related from the levels of phrases,clauses, sentences and paragraphs, to the level of the body of contentas a whole and to its language-independent meaning. In certainembodiments, the semantic analysis 202 process includes processing atarget sentence to parse it into its individual parts of speech, tagsentence elements that are related to predetermined items of interest,identify dependencies between individual words, and perform co-referenceresolution. For example, if a sentence states that the author reallylikes the hamburgers served by a particular restaurant, then the name ofthe “particular restaurant” is co-referenced to “hamburgers.”

As likewise used herein, goal optimization 204 broadly refers toperforming multi-criteria decision making operations to achieve a givengoal or target objective. In various embodiments, one or more goaloptimization 204 processes are implemented by the CILS 118 to definepredetermined goals, which in turn contribute to the generation of acognitive insight. For example, goals for planning a vacation trip mayinclude low cost (e.g., transportation and accommodations), location(e.g., by the beach), and speed (e.g., short travel time). In thisexample, it will be appreciated that certain goals may be in conflictwith another. As a result, a cognitive insight provided by the CILS 118to a traveler may indicate that hotel accommodations by a beach may costmore than they care to spend.

Collaborative filtering 206, as used herein, broadly refers to theprocess of filtering for information or patterns through thecollaborative involvement of multiple agents, viewpoints, data sources,and so forth. The application of such collaborative filtering 206processes typically involves very large and different kinds of datasets, including sensing and monitoring data, financial data, and userdata of various kinds collaborative filtering 206 may also refer to theprocess of making automatic predictions associated with predeterminedinterests of a user by collecting preferences or other information frommany users. For example, if person ‘A’ has the same opinion as a person‘B’ for a given issue ‘x’, then an assertion can be made that person ‘A’is more likely to have the same opinion as person ‘B’ opinion on adifferent issue ‘y’ than to have the same opinion on issue ‘y’ as arandomly chosen person. In various embodiments, the collaborativefiltering 206 process is implemented with various recommendation enginesfamiliar to those of skill in the art to make recommendations.

As used herein, common sense reasoning 208 broadly refers to simulatingthe human ability to make deductions from common facts they inherentlyknow. Such deductions may be made from inherent knowledge about thephysical properties, purpose, intentions and possible behavior ofordinary things, such as people, animals, objects, devices, and so on.In various embodiments, common sense reasoning 208 processes areimplemented to assist the CILS 118 in understanding and disambiguatingwords within a predetermined context. In certain embodiments, the commonsense reasoning 208 processes are implemented to allow the CILS 118 togenerate text or phrases related to a target word or phrase to performdeeper searches for the same terms. It will be appreciated that if thecontext of a word is better understood, then a common senseunderstanding of the word can then be used to assist in finding betteror more accurate information. In certain embodiments, this better ormore accurate understanding of the context of a word, and its relatedinformation, allows the CILS 118 to make more accurate deductions, whichare in turn used to generate cognitive insights.

As likewise used herein, natural language processing (NLP) 210 broadlyrefers to interactions with a system, such as the CILS 118, through theuse of human, or natural, languages. In various embodiments, various NLP210 processes are implemented by the CILS 118 to achieve naturallanguage understanding, which enables it to not only derive meaning fromhuman or natural language input, but to also generate natural languageoutput.

Summarization 212, as used herein, broadly refers to processing a set ofinformation, organizing and ranking it, and then generating acorresponding summary. As an example, a news article may be processed toidentify its primary topic and associated observations, which are thenextracted, ranked, and then presented to the user. As another example,page ranking operations may be performed on the same news article toidentify individual sentences, rank them, order them, and determinewhich of the sentences are most impactful in describing the article andits content. As yet another example, a structured data record, such as apatient's electronic medical record (EMR), may be processed using thesummarization 212 process to generate sentences and phrases thatdescribes the content of the EMR. In various embodiments, varioussummarization 212 processes are implemented by the CILS 118 to generatesummarizations of content streams, which are in turn used to generatecognitive insights.

As used herein, temporal/spatial reasoning 214 broadly refers toreasoning based upon qualitative abstractions of temporal and spatialaspects of common sense knowledge, described in greater detail herein.For example, it is not uncommon for a predetermined set of data tochange over time. Likewise, other attributes, such as its associatedmetadata, may likewise change over time. As a result, these changes mayaffect the context of the data. To further the example, the context ofasking someone what they believe they should be doing at 3:00 in theafternoon during the workday while they are at work may be quitedifferent that asking the same user the same question at 3:00 on aSunday afternoon when they are at home. In various embodiments, varioustemporal/spatial reasoning 214 processes are implemented by the CILS 118to determine the context of queries, and associated data, which are inturn used to generate cognitive insights.

As likewise used herein, entity resolution 216 broadly refers to theprocess of finding elements in a set of data that refer to the sameentity across different data sources (e.g., structured, non-structured,streams, devices, etc.), where the target entity does not share a commonidentifier. In various embodiments, the entity resolution 216 process isimplemented by the CILS 118 to identify significant nouns, adjectives,phrases or sentence elements that represent various predeterminedentities within one or more domains. From the foregoing, it will beappreciated that the implementation of one or more of the semanticanalysis 202, goal optimization 204, collaborative filtering 206, commonsense reasoning 208, natural language processing 210, summarization 212,temporal/spatial reasoning 214, and entity resolution 216 processes bythe CILS 118 can facilitate the generation of a semantic, cognitivemodel.

In various embodiments, the CILS 118 receives ambient signals 220,curated data 222, and learned knowledge, which is then processed by theCILS 118 to generate one or more cognitive graphs 226. In turn, the oneor more cognitive graphs 226 are further used by the CILS 118 togenerate cognitive insight streams, which are then delivered to one ormore destinations 230, as described in greater detail herein.

As used herein, ambient signals 220 broadly refer to input signals, orother data streams, that may contain data providing additional insightor context to the curated data 222 and learned knowledge 224 received bythe CILS 118. For example, ambient signals may allow the CILS 118 tounderstand that a user is currently using their mobile device, atlocation ‘x’, at time ‘y’, doing activity ‘z’. To further the example,there is a difference between the user using their mobile device whilethey are on an airplane versus using their mobile device after landingat an airport and walking between one terminal and another. To extendthe example even further, ambient signals may add additional context,such as the user is in the middle of a three leg trip and has two hoursbefore their next flight. Further, they may be in terminal A1, but theirnext flight is out of C1, it is lunchtime, and they want to know thebest place to eat. Given the available time the user has, their currentlocation, restaurants that are proximate to their predicted route, andother factors such as food preferences, the CILS 118 can perform variouscognitive operations and provide a recommendation for where the user caneat.

In various embodiments, the curated data 222 may include structured,unstructured, social, public, private, streaming, device or other typesof data described in greater detail herein. In certain embodiments, thelearned knowledge 224 is based upon past observations and feedback fromthe presentation of prior cognitive insight streams and recommendations.In various embodiments, the learned knowledge 224 is provided via afeedback look that provides the learned knowledge 224 in the form of alearning stream of data.

As likewise used herein, a cognitive graph 226 refers to arepresentation of expert knowledge, associated with individuals andgroups over a period of time, to depict relationships between people,places, and things using words, ideas, audio and images. As such, it isa machine-readable formalism for knowledge representation that providesa common framework allowing data and knowledge to be shared and reusedacross user, application, organization, and community boundaries.

In various embodiments, the information contained in, and referenced by,a cognitive graph 226 is derived from many sources (e.g., public,private, social, device), such as curated data 222. In certain of theseembodiments, the cognitive graph 226 assists in the identification andorganization of information associated with how people, places andthings are related to one other. In various embodiments, the cognitivegraph 226 enables automated agents, described in greater detail herein,to access the Web more intelligently, enumerate inferences throughutilization of curated, structured data 222, and provide answers toquestions by serving as a computational knowledge engine.

In certain embodiments, the cognitive graph 226 not only elicits andmaps expert knowledge by deriving associations from data, it alsorenders higher level insights and accounts for knowledge creationthrough collaborative knowledge modeling. In various embodiments, thecognitive graph 226 is a machine-readable, declarative memory systemthat stores and learns both episodic memory (e.g., specific personalexperiences associated with an individual or entity), and semanticmemory, which stores factual information (e.g., geo location of anairport or restaurant).

For example, the cognitive graph 226 may know that a given airport is aplace, and that there is a list of related places such as hotels,restaurants and departure gates. Furthermore, the cognitive graph 226may know that people such as business travelers, families and collegestudents use the airport to board flights from various carriers, eat atvarious restaurants, or shop at certain retail stores. The cognitivegraph 226 may also have knowledge about the key attributes from variousretail rating sites that travelers have used to describe the food andtheir experience at various venues in the airport over the past sixmonths.

In certain embodiments, the cognitive insight stream 228 isbidirectional, and supports flows of information both too and fromdestinations 230. In these embodiments, the first flow is generated inresponse to receiving a query, and subsequently delivered to one or moredestinations 230. The second flow is generated in response to detectinginformation about a user of one or more of the destinations 230. Suchuse results in the provision of information to the CILS 118. Inresponse, the CILS 118 processes that information, in the context ofwhat it knows about the user, and provides additional information to theuser, such as a recommendation. In various embodiments, the cognitiveinsight stream 228 is configured to be provided in a “push” streamconfiguration familiar to those of skill in the art. In certainembodiments, the cognitive insight stream 228 is implemented to usenatural language approaches familiar to skilled practitioners of the artto support interactions with a user.

In various embodiments, the cognitive insight stream 228 may include astream of visualized insights. As used herein, visualized insightsbroadly refers to cognitive insights that are presented in a visualmanner, such as a map, an infographic, images, and so forth. In certainembodiments, these visualized insights may include various cognitiveinsights, such as “What happened?”, “What do I know about it?”, “What islikely to happen next?”, or “What should I do about it?” In theseembodiments, the cognitive insight stream is generated by variouscognitive agents, which are applied to various sources, datasets, andcognitive graphs. As used herein, a cognitive agent broadly refers to acomputer program that performs a task with minimum specific directionsfrom users and learns from each interaction with data and human users.

In various embodiments, the CILS 118 delivers Cognition as a Service(CaaS). As such, it provides a cloud-based development and executionplatform that allow various cognitive applications and services tofunction more intelligently and intuitively. In certain embodiments,cognitive applications powered by the CILS 118 are able to think andinteract with users as intelligent virtual assistants. As a result,users are able to interact with such cognitive applications by askingthem questions and giving them commands. In response, these cognitiveapplications will be able to assist the user in completing tasks andmanaging their work more efficiently.

In these and other embodiments, the CILS 118 can operate as an analyticsplatform to process big data, and dark data as well, to provide dataanalytics through a public, private or hybrid cloud environment. As usedherein, cloud analytics broadly refers to a service model wherein datasources, data models, processing applications, computing power, analyticmodels, and sharing or storage of results are implemented within a cloudenvironment to perform one or more aspects of analytics.

In various embodiments, users submit queries and computation requests ina natural language format to the CILS 118. In response, they areprovided with a ranked list of relevant answers and aggregatedinformation with useful links and pertinent visualizations through agraphical representation. In these embodiments, the cognitive graph 226generates semantic and temporal maps to reflect the organization ofunstructured data and to facilitate meaningful learning from potentiallymillions of lines of text, much in the same way as arbitrary syllablesstrung together create meaning through the concept of language.

FIG. 3 is a simplified block diagram of a cognitive inference andlearning system (CILS) reference model implemented in accordance with anembodiment of the invention. In this embodiment, the CILS referencemodel is associated with the CILS 118 shown in FIG. 2. As shown in FIG.3, the CILS 118 includes client applications 302, applicationaccelerators 306, a cognitive platform 310, and cloud infrastructure340. In various embodiments, the client applications 302 includecognitive applications 304, which are implemented to understand andadapt to the user, not the other way around, by natively accepting andunderstanding human forms of communication, such as natural languagetext, audio, images, video, and so forth.

In these and other embodiments, the cognitive applications 304 possesssituational and temporal awareness based upon ambient signals from usersand data, which facilitates understanding the user's intent, content,context and meaning to drive goal-driven dialogs and outcomes. Further,they are designed to gain knowledge over time from a wide variety ofstructured, non-structured, and device data sources, continuouslyinterpreting and autonomously reprogramming themselves to betterunderstand a given domain. As such, they are well-suited to supporthuman decision making, by proactively providing trusted advice, offersand recommendations while respecting user privacy and permissions.

In various embodiments, the application accelerators 306 include acognitive application framework 308. In certain embodiments, theapplication accelerators 306 and the cognitive application framework 308support various plug-ins and components that facilitate the creation ofclient applications 302 and cognitive applications 304. In variousembodiments, the application accelerators 306 include widgets, userinterface (UI) components, reports, charts, and back-end integrationcomponents familiar to those of skill in the art.

As likewise shown in FIG. 3, the cognitive platform 310 includes amanagement console 312, a development environment 314, applicationprogram interfaces (APIs) 316, sourcing agents 318, a cognitive engine320, destination agents 336, and platform data 338, all of which aredescribed in greater detail herein. In various embodiments, themanagement console 312 is implemented to manage accounts and projects,along with user-specific metadata that is used to drive processes andoperations within the cognitive platform 310 for a predeterminedproject.

In certain embodiments, the development environment 314 is implementedto create custom extensions to the CILS 118 shown in FIG. 2. In variousembodiments, the development environment 314 is implemented for thedevelopment of a custom application, which may subsequently be deployedin a public, private or hybrid cloud environment.

FIG. 5 is a simplified process diagram of cognitive inference andlearning system (CILS) operations performed in accordance with anembodiment of the invention. In various embodiments, these CILSoperations may include a perceive 506 phase, a relate 508 phase, anoperate 510 phase, a process and execute 512 phase, and a learn 514phase. In these and other embodiments, the CILS 118 shown in FIG. 2 isimplemented to mimic cognitive processes associated with the humanbrain. In various embodiments, the CILS operations are performed throughthe implementation of a cognitive platform 310, described in greaterdetail herein. In these and other embodiments, the cognitive platform310 may be implemented within a cloud analytics infrastructure 344,which in turn is implemented within a cloud infrastructure 340, likewisedescribed in greater detail herein.

In various embodiments, multi-site, multi-structured source streams 504are provided by sourcing agents, as described in greater detail herein.In these embodiments, the source streams 504 are dynamically ingested inreal-time during the perceive 506 phase, and based upon a predeterminedcontext, extraction, parsing, and tagging operations are performed onlanguage, text and images contained in the source streams 504. Automaticfeature extraction and modeling operations are then performed with thepreviously processed source streams 504 during the relate 508 phase togenerate queries to identify related data (i.e., corpus expansion).

In various embodiments, operations are performed during the operate 510phase to discover, summarize and prioritize various concepts, which arein turn used to generate actionable recommendations and notificationsassociated with predetermined plan-based optimization goals. Theresulting actionable recommendations and notifications are thenprocessed during the process and execute 512 phase to provide cognitiveinsights, such as recommendations, to various predetermined destinationsand associated application programming interfaces (APIs) 524.

In various embodiments, features from newly-observed data areautomatically extracted from user feedback during the learn 514 phase toimprove various analytical models. In these embodiments, the learn 514phase includes feedback on observations generated during the relate 508phase, which is provided to the perceive 506 phase. Likewise, feedbackon decisions resulting from operations performed during the operate 510phase, and feedback on results resulting from operations performedduring the process and execute 512 phase, are also provided to theperceive 506 phase.

In various embodiments, user interactions result from operationsperformed during the process and execute 512 phase. In theseembodiments, data associated with the user interactions are provided tothe perceive 506 phase as unfolding interactions 522, which includeevents that occur external to the CILS operations described in greaterdetail herein. As an example, a first query from a user may be submittedto the CILS system, which in turn generates a first cognitive insight,which is then provided to the user. In response, the user may respond byproviding a first response, or perhaps a second query, either of whichis provided in the same context as the first query. The CILS receivesthe first response or second query, performs various CILS operations,and provides the user a second cognitive insight. As before, the usermay respond with a second response or a third query, again in thecontext of the first query. Once again, the CILS performs various CILSoperations and provides the user a third cognitive insight, and soforth. In this example, the provision of cognitive insights to the user,and their various associated responses, results in unfoldinginteractions 522, which in turn result in a stateful dialog that evolvesover time. Skilled practitioners of the art will likewise realize thatsuch unfolding interactions 522, occur outside of the CILS operationsperformed by the cognitive platform 310.

In these embodiments, the sourcing 318 agent isimplemented to source a variety of multi-site, multi-structured sourcestreams of data described in greater detail herein. These sourced datastreams are then provided to an enrichment 425 agent, which then invokesan enrichment component to perform enrichment operations to generateenriched data streams, likewise described in greater detail herein.

The enriched data streams are then provided to a bridging 429 agent,which is used to perform bridging operations described in greater detailherein. In turn, the results of the bridging operations are provided toan insight 433 agent, which is implemented as described in greaterdetail herein to create a visual data story, highlighting user-specificinsights, relationships and recommendations. The resulting visual datastory is then provided to a destination 336 agent, which is implementedto publish cognitive insights to a consumer of cognitive insight data,likewise as described in greater detail herein. In response, theconsumer of cognitive insight data provides feedback to a learning 434agent, which is implemented as described in greater detail herein toprovide the feedback to the sourcing agent 318, at which point the CILSagents lifecycle 602 is continued. From the foregoing, skilledpractitioners of the art will recognize that each iteration of thecognitive agents lifecycle 602 provides more informed cognitiveinsights.

In these embodiments,the knowledge elements may be explicit or implicit. As an example, thefact that water freezes at zero degrees centigrade would be an explicitknowledge element, while the fact that an automobile mechanic knows howto repair an automobile would be an implicit knowledge element.

In certain embodiments, the knowledge elements within a universalknowledge repository may also include statements, assertions, beliefs,perceptions, preferences, sentiments, attitudes or opinions associatedwith a person or a group. As an example, user ‘A’ may prefer the pizzaserved by a first restaurant, while user ‘B’ may prefer the pizza servedby a second restaurant. Furthermore, both user ‘A’ and ‘B’ are firmly ofthe opinion that the first and second restaurants respectively serve thevery best pizza available. In this example, the respective preferencesand opinions of users ‘A’ and B′ regarding the first and secondrestaurant may be included in the universal knowledge repository 880 asthey are not contradictory. Instead, they are simply knowledge elementsrespectively associated with the two users and can be used in variousembodiments for the generation of various cognitive insights, asdescribed in greater detail herein.

In various embodiments, individual knowledge elements respectivelyassociated with the hosted 718 and private 728 universal knowledgerepositories may be distributed. In one embodiment, the distributedknowledge elements may be stored in a plurality of data stores familiarto skilled practitioners of the art.

Incertain embodiments, the hosted 718 and private 728 universal knowledgerepositories may be respectively implemented in the form of a hosted orprivate universal cognitive graph. In these embodiments, nodes withinthe hosted or private universal graph contain one or more knowledgeelements.

In various embodiments, a secure tunnel 730, such as a virtual privatenetwork (VPN) tunnel, is implemented to allow the hosted 710 cognitiveplatform and the private 720 cognitive platform to communicate with oneanother. In these various embodiments, the ability to communicate withone another allows the hosted 710 and private 720 cognitive platforms towork collaboratively when generating cognitive insights described ingreater detail herein. In various embodiments, the hosted 710 cognitiveplatform accesses knowledge elements stored in the hosted 718 universalknowledge repository and data stored in the repositories of curatedpublic data 714 and licensed data 716 to generate various cognitiveinsights. In certain embodiments, the resulting cognitive insights arethen provided to the private 720 cognitive platform, which in turnprovides them to the one or more private cognitive applications 736.

In various embodiments, the private 720 cognitive platform accessesknowledge elements stored in the private 728 universal knowledgerepository and data stored in the repositories of application data 724and private data 726 to generate various cognitive insights. In turn,the resulting cognitive insights are then provided to the one or moreprivate cognitive applications 736. In certain embodiments, the private720 cognitive platform accesses knowledge elements stored in the hosted718 and private 728 universal knowledge repositories and data stored inthe repositories of curated public data 714, licensed data 716,application data 724 and private data 726 to generate various cognitiveinsights. In these embodiments, the resulting cognitive insights are inturn provided to the one or more private cognitive applications 736.

In various embodiments, the secure tunnel 730 is implemented for thehosted 710 cognitive platform to provide 732 predetermined data andknowledge elements to the private 720 cognitive platform. In oneembodiment, the provision 732 of predetermined knowledge elements allowsthe hosted 718 universal knowledge repository to be replicated as theprivate 728 universal knowledge repository. In another embodiment, theprovision 732 of predetermined knowledge elements allows the hosted 718universal knowledge repository to provide updates 734 to the private 728universal knowledge repository. In certain embodiments, the updates 734to the private 728 universal knowledge repository do not overwrite otherdata. Instead, the updates 734 are simply added to the private 728universal knowledge repository.

In one embodiment, knowledge elements that are added to the private 728universal knowledge repository are not provided to the hosted 718universal knowledge repository. As an example, an airline may not wishto share private information related to its customer's flights, theprice paid for tickets, their awards program status, and so forth. Inanother embodiment, predetermined knowledge elements that are added tothe private 728 universal knowledge repository may be provided to thehosted 718 universal knowledge repository. As an example, the operatorof the private 720 cognitive platform may decide to licensepredetermined knowledge elements stored in the private 728 universalknowledge repository to the operator of the hosted 710 cognitiveplatform. To continue the example, certain knowledge elements stored inthe private 728 universal knowledge repository may be anonymized priorto being provided for inclusion in the hosted 718 universal knowledgerepository. In one embodiment, only private knowledge elements arestored in the private 728 universal knowledge repository. In thisembodiment, the private 720 cognitive platform may use knowledgeelements stored in both the hosted 718 and private 728 universalknowledge repositories to generate cognitive insights. Skilledpractitioners of the art will recognize that many such embodiments arepossible and the foregoing is not intended to limit the spirit, scope orintent of the invention.

In various embodiments, a cognitive application 304 is implemented toreceive input data 1242 associated with an individual user or a group ofusers. In these embodiments, the input data 1242 may be direct, such asa user query or mouse click, or indirect, such as the current time orGeographical Positioning System (GPS) data received from a mobile deviceassociated with a user. In various embodiments, the indirect input data1242 may include contextual data, described in greater detail herein.Once it is received, the input data 1242 is then submitted by thecognitive application 304 to a graph query engine 326 during theapplication/insight composition 1240 phase. In turn, the graph queryengine 326 processes the submitted input data 1242 to generate a graphquery 1244, as described in greater detail herein. The graph query 1244is then used to query the application cognitive graph 1282, whichresults in the generation of one or more composite cognitive insights,likewise described in greater detail herein. In certain embodiments, thegraph query 1244 uses predetermined knowledge elements stored in theuniversal knowledge repository 1280 when querying the applicationcognitive graph 1282 to generate the one or more composite cognitiveinsights.

In various embodiments, the graph query 1244 results in the selection ofa predetermined cognitive persona, described in greater detail herein,from a repository of cognitive personas ‘1’ through ‘n’ 1272, accordingto a set of contextual information associated with a user. In certainembodiments, the universal knowledge repository 1280 includes therepository of personas ‘1’ through ‘n’ 1272. In various embodiments,individual nodes within predetermined cognitive personas stored in therepository of personas ‘1’ through ‘n’ 1272 are linked 954 tocorresponding nodes in the universal knowledge repository 1280. Incertain embodiments, predetermined nodes within the universal knowledgerepository 1280 are likewise linked to predetermined nodes within thecognitive application graph 1282.

As used herein, contextual information broadly refers to informationassociated with a location, a point in time, a user role, an activity, acircumstance, an interest, a desire, a perception, an objective, or acombination thereof. In certain embodiments, the contextual informationis likewise used in combination with the selected cognitive persona togenerate one or more composite cognitive insights for a user. In variousembodiments, the composite cognitive insights that are generated for auser as a result of using a first set of contextual information may bedifferent than the composite cognitive insights that are generated as aresult of using a second set of contextual information.

As an example, a user may have two associated cognitive personas,“purchasing agent” and “retail shopper,” which are respectively selectedaccording to two sets of contextual information. In this example, the“purchasing agent” cognitive persona may be selected according to afirst set of contextual information associated with the user performingbusiness purchasing activities in their office during business hours,with the objective of finding the best price for a particular commercialinventory item. Conversely, the “retail shopper” cognitive persona maybe selected according to a second set of contextual informationassociated with the user performing cognitive personal shoppingactivities in their home over a weekend, with the objective of finding adecorative item that most closely matches their current furnishings. Asa result, the composite cognitive insights generated as a result ofcombining the first cognitive persona with the first set of contextualinformation will likely be different than the composite cognitiveinsights generated as a result of combining the second cognitive personawith the second set of contextual information.

In various embodiments, the graph query 1244 results in the selection ofa predetermined cognitive profile, described in greater detail herein,from a repository of cognitive profiles ‘1’ through ‘n’ 1274 accordingto identification information associated with a user. The method bywhich the identification information is determined is a matter of designchoice. In certain embodiments, set of contextual information associatedwith a user is used to select the cognitive profile is selected from therepository of cognitive profiles ‘1’ through ‘n’ 1274. In variousembodiments, one or more cognitive profiles may be associated with apredetermined user. In these embodiments, a predetermined cognitiveprofile is selected and then used by a CILS to generate one or morecomposite cognitive insights for the user as described in greater detailherein. In certain of these embodiments, the selected cognitive profileprovides a basis for adaptive changes to the CILS, and by extension, thecomposite cognitive insights it generates.

In various embodiments, provision of the composite cognitive insightsresults in the CILS receiving feedback 1262 information related to anindividual user. In one embodiment, the feedback 1262 information isused to revise or modify a cognitive persona. In another embodiment, thefeedback 1262 information is used to revise or modify the cognitiveprofile associated with a user. In yet another embodiment, the feedback1262 information is used to create a new cognitive profile, which inturn is stored in the repository of cognitive profiles ‘1’ through ‘n’1274. In still yet another embodiment, the feedback 1262 information isused to create one or more associated cognitive profiles, which inherita common set of attributes from a source cognitive profile. In anotherembodiment, the feedback 1262 information is used to create a newcognitive profile that combines attributes from two or more sourcecognitive profiles. In various embodiments, these persona and profilemanagement operations 1276 are performed through interactions betweenthe cognitive application 304, the repository of cognitive personas ‘1’through ‘n’ 1272, the repository of cognitive profiles ‘1’ through ‘n’1274, the universal knowledge repository 1280, or some combinationthereof. Those of skill in the art will realize that many suchembodiments are possible and the foregoing is not intended to limit thespirit, scope or intent of the invention.

In various embodiments, a cognitive profile associated with a user maybe either static or dynamic. As used herein, a static cognitive profilerefers to a cognitive profile that contains identification informationassociated with a user that changes on an infrequent basis. As anexample, a user's name, Social Security Number (SSN), or passport numbermay not change, although their age, address or employer may change overtime. To continue the example, the user may likewise have a variety offinancial account identifiers and various travel awards programidentifiers which change infrequently.

As likewise used herein, a dynamic cognitive profile refers to acognitive profile that contains information associated with a user thatchanges on a dynamic basis. For example, a user's interests andactivities may evolve over time, which may be evidenced by associatedinteractions with the CILS. In various embodiments, these interactionsresult in the provision of associated composite cognitive insights tothe user. In these embodiments, the user's interactions with the CILS,and the resulting composite cognitive insights that are generated, areused to update the dynamic cognitive profile on an ongoing basis toprovide an up-to-date representation of the user in the context of thecognitive profile used to generate the composite cognitive insights.

In various embodiments, a cognitive profile, whether static or dynamic,is selected according to a set of contextual information associated witha user. In certain embodiments, the contextual information is likewiseused in combination with the selected cognitive profile to generate oneor more composite cognitive insights for the user. In these embodiments,the composite cognitive insights that are generated as a result of usinga first set of contextual information with the selected cognitiveprofile may be different than the composite cognitive insights that aregenerated as a result of using a second set of contextual information.

As an example, a user may have two associated cognitive profiles,“runner” and “foodie,” which are respectively selected according to twosets of contextual information. In this example, the “runner” cognitiveprofile may be selected according to a first set of contextualinformation associated with the user being out of town on businesstravel and wanting to find a convenient place to run close to where theyare staying. To continue this example, two composite cognitive insightsmay be generated and provided to the user in the form of a cognitiveinsight summary 1248. The first may be suggesting a running trail theuser has used before and liked, but needs directions to find again. Thesecond may be suggesting a new running trail that is equally convenient,but wasn't available the last time the user was in town.

Conversely, the “foodie” cognitive profile may be selected according toa second set of contextual information associated with the user being athome and expressing an interest in trying either a new restaurant or aninnovative cuisine. To further continue this example, the user's“foodie” cognitive profile may be processed by the CILS to determinewhich restaurants and cuisines the user has tried in the last eighteenmonths. As a result, two composite cognitive insights may be generatedand provided to the user in the form of a cognitive insight summary1248. The first may be a suggestion for a new restaurant that is servinga cuisine the user has enjoyed in the past. The second may be asuggestion for a restaurant familiar to the user that is promoting aseasonal menu featuring Asian fusion dishes, which the user has nottried before. Those of skill in the art will realize that the compositecognitive insights generated as a result of combining the firstcognitive profile with the first set of contextual information willlikely be different than the composite cognitive insights generated as aresult of combining the second cognitive profile with the second set ofcontextual information.

In various embodiments, a user's cognitive profile, whether static ordynamic, may reference data that is proprietary to the user, anorganization, or a combination thereof. As used herein, proprietary databroadly refers to data that is owned, controlled, or a combinationthereof, by an individual user or an organization, which is deemedimportant enough that it gives competitive advantage to that individualor organization. In certain embodiments, the organization may be agovernmental, non-profit, academic or social entity, a manufacturer, awholesaler, a retailer, a service provider, an operator of a cognitiveinference and learning system (CILS), and others.

In various embodiments, an organization may or may not grant a user theright to obtain a copy of certain proprietary information referenced bytheir cognitive profile. In certain embodiments, a first organizationmay or may not grant a user the right to obtain a copy of certainproprietary information referenced by their cognitive profile andprovide it to a second organization. As an example, the user may not begranted the right to provide travel detail information (e.g., traveldates and destinations, etc.) associated with an awards program providedby a first travel services provider (e.g., an airline, a hotel chain, acruise ship line, etc.) to a second travel services provider. In variousembodiments, the user may or may not grant a first organization theright to provide a copy of certain proprietary information referenced bytheir cognitive profile to a second organization. Those of skill in theart will recognize that many such embodiments are possible and theforegoing is not intended to limit the spirit, scope or intent of theinvention.

In various embodiments, a set of contextually-related interactionsbetween a cognitive application 304 and the application cognitive graph1282 are represented as a corresponding set of nodes in a predeterminedcognitive session graph, which is then stored in a repository ofcognitive session graphs ‘1’ through ‘n’ 1252. As used herein, acognitive session graph broadly refers to a cognitive graph whose nodesare associated with a cognitive session. As used herein, a cognitivesession broadly refers to a predetermined user, group of users, theme,topic, issue, question, intent, goal, objective, task, assignment,process, situation, requirement, condition, responsibility, location,period of time, or any combination thereof.

As an example, the application cognitive graph 1282 may be unaware of aparticular user's preferences, which are likely stored in acorresponding user profile. To further the example, a user may typicallychoose a particular brand or manufacturer when shopping for a given typeof product, such as cookware. A record of each query regarding thatbrand of cookware, or its selection, is iteratively stored in apredetermined session graph that is associated with the user and storedin a repository of session graphs ‘1’ through ‘n’ 1252. As a result, thepreference of that brand of cookware is ranked higher, and is presentedin response to contextually-related queries, even when the preferredbrand of cookware is not explicitly referenced by the user. To continuethe example, the user may make a number of queries over a period of daysor weeks, yet the queries are all associated with the same cognitivesession graph that is associated with the user and stored in arepository of cognitive session graphs ‘1’ through ‘n’ 1252, regardlessof when each query is made.

As another example, a user queries a cognitive application 304 duringbusiness hours to locate an upscale restaurant located close their placeof business. As a result, a first cognitive session graph stored in arepository of cognitive session graphs ‘1’ through ‘n’ 1252 isassociated with the user's query, which results in the provision ofcomposite cognitive insights related to restaurants suitable forbusiness meetings. To continue the example, the same user queries thesame cognitive application 304 during the weekend to locate a casualrestaurant located close to their home. As a result, a second cognitivesession graph stored in a repository of cognitive session graphs ‘1’through ‘n’ 1252 is associated with the user's query, which results inthe provision of composite cognitive insights related to restaurantssuitable for family meals. In these examples, the first and secondcognitive session graphs are both associated with the same user, but fortwo different purposes, which results in the provision of two differentsets of composite cognitive insights.

As yet another example, a group of customer support representatives istasked with resolving technical issues customers may have with apredetermined product. In this example, the product and the group ofcustomer support representatives are collectively associated with apredetermined cognitive session graph stored in a repository ofcognitive session graphs ‘1’ through ‘n’ 1252. To continue the example,individual customer support representatives may submit queries relatedto the product to a cognitive application 304, such as a knowledge baseapplication. In response, a predetermined cognitive session graph storedin a repository of cognitive session graphs ‘1’ through ‘n’ 1252 isused, along with the universal knowledge repository 880 and applicationcognitive graph 1282, to generate individual or composite cognitiveinsights to resolve a technical issue for a customer. In this example,the cognitive application 304 may be queried by the individual customersupport representatives at different times during some predeterminedtime interval, yet the same cognitive session graph stored in arepository of cognitive session graphs ‘1’ through ‘n’ 1252 is used togenerate composite cognitive insights related to the product.

In various embodiments, each cognitive session graph associated with auser and stored in a repository of cognitive session graphs ‘1’ through‘n’ 1252 includes one or more direct or indirect user queriesrepresented as nodes, and the time at which they were asked, which arein turn linked 1254 to nodes that appear in the application cognitivegraph 1282. In certain embodiments, each individual session graph thatis associated with the user and stored in a repository of session graphs‘1’ through ‘n’ 1252 introduces edges that are not already present inthe application cognitive graph 1282. More specifically, each of thesession graphs that is associated with the user and stored in arepository of session graphs ‘1’ through ‘n’ 1252 establishes variousrelationships that the application cognitive graph 1282 does not alreadyhave.

In various embodiments, individual cognitive profiles in the repositoryof profiles ‘1’ through ‘n’ 1274 are respectively stored as sessiongraphs in the repository of session graphs 1252. In these embodiments,predetermined nodes within each of the individual cognitive profiles arelinked 1254 to predetermined nodes within corresponding cognitivesession graphs stored in the repository of cognitive session graphs ‘1’through ‘n’ 1254. In certain embodiments, individual nodes within eachof the cognitive profiles are likewise linked 1254 to correspondingnodes within various cognitive personas stored in the repository ofcognitive personas ‘1’ through ‘n’ 1272.

In various embodiments, individual graph queries 1244 associated with apredetermined session graph stored in a repository of session graphs ‘1’through ‘n’ 1252 are likewise provided to predetermined insight agentsto perform various kinds of analyses. In certain embodiments, eachinsight agent performs a different kind of analysis. In variousembodiments, different insight agents may perform the same, or similar,analyses. In certain embodiments, different agents performing the sameor similar analyses may be competing between themselves.

For example, a user may be a realtor that has a young, uppermiddle-class, urban-oriented clientele that typically enjoys eating attrendy restaurants that are in walking distance of where they live. As aresult, the realtor may be interested in knowing about new or popularrestaurants that are in walking distance of their property listings thathave a young, middle-class clientele. In this example, the user'squeries may result the assignment of predetermined insight agents toperform analysis of various social media interactions to identify suchrestaurants that have received favorable reviews. To continue theexample, the resulting composite insights may be provided as a rankedlist of candidate restaurants that may be suitable venues for therealtor to meet his clients.

In various embodiments, the process 1208 component is implemented toprovide these composite cognitive insights to the deliver 1210component, which in turn is implemented to deliver the compositecognitive insights in the form of a cognitive insight summary 1248 tothe cognitive application 304. In these embodiments, the cognitiveplatform 1210 is implemented to interact with an insight front-end 1256component, which provides a composite insight and feedback interfacewith the cognitive application 304. In certain embodiments, the insightfront-end 1256 component includes an insight Application ProgramInterface (API) 1258 and a feedback API 1260, described in greaterdetail herein. In these embodiments, the insight API 1258 is implementedto convey the cognitive insight summary 1248 to the cognitiveapplication 304. Likewise, the feedback API 1260 is used to conveyassociated direct or indirect user feedback 1262 to the cognitiveplatform 1210. In certain embodiments, the feedback API 1260 providesthe direct or indirect user feedback 1262 to the repository of models1228 described in greater detail herein.

To continue the preceding example, the user may have received a list ofcandidate restaurants that may be suitable venues for meeting hisclients. However, one of his clients has a pet that they like to takewith them wherever they go. As a result, the user provides feedback 1262that he is looking for a restaurant that is pet-friendly. The providedfeedback 1262 is in turn provided to the insight agents to identifycandidate restaurants that are also pet-friendly. In this example, thefeedback 1262 is stored in the appropriate session graph 1252 associatedwith the user and their original query.

In various embodiments, as described in the descriptive text associatedwith FIG. 5, learning operations are iteratively performed during thelearning 1238 phase to provide more accurate and useful compositecognitive insights. In certain of these embodiments, feedback 1262received from the user is stored in a predetermined session graph thatis associated with the user and stored in a repository of session graphs‘1’ through ‘n’ 1252, which is then used to provide more accuratecomposite cognitive insights in response to subsequentcontextually-relevant queries from the user.

As an example, composite cognitive insights provided by a particularinsight agent related to a first subject may not be relevant orparticularly useful to a user of the cognitive application 304. As aresult, the user provides feedback 1262 to that effect, which in turn isstored in the appropriate session graph that is associated with the userand stored in a repository of session graphs ‘1’ through ‘n’ 1252.Accordingly, subsequent insights provided by the insight agent relatedthe first subject may be ranked lower, or not provided, within acognitive insight summary 1248 provided to the user. Conversely, thesame insight agent may provide excellent insights related to a secondsubject, resulting in positive feedback 1262 being received from theuser. The positive feedback 1262 is likewise stored in the appropriatesession graph that is associated with the user and stored in arepository of session graphs ‘1’ through ‘n’ 1252. As a result,subsequent insights provided by the insight agent related to the secondsubject may be ranked higher within a cognitive insight summary 1248provided to the user.

In various embodiments, the composite insights provided in eachcognitive insight summary 1248 to the cognitive application 304, andcorresponding feedback 1262 received from a user in return, is providedin the form of one or more insight streams 1264 to an associated sessiongraph stored in a repository of session graphs ‘1’ through ‘n’ 1252. Inthese and other embodiments, the insight streams 1264 may containinformation related to the user of the cognitive application 304, thetime and date of the provided composite cognitive insights and relatedfeedback 1262, the location of the user, and the device used by theuser.

As an example, a query related to upcoming activities that is receivedat 10:00 AM on a Saturday morning from a user's home may returncomposite cognitive insights related to entertainment performancesscheduled for the weekend. Conversely, the same query received at thesame time on a Monday morning from a user's office may return compositecognitive insights related to business functions scheduled during thework week. In various embodiments, the information contained in theinsight streams 1264 is used to rank the composite cognitive insightsprovided in the cognitive insight summary 1248. In certain embodiments,the composite cognitive insights are continually re-ranked as additionalinsight streams 1264 are received. Skilled practitioners of the art willrecognize that many such embodiments are possible and the foregoing isnot intended to limit the spirit, scope or intent of the invention.

FIGS. 13a and 13b are a generalized flowchart of cognitive persona andcognitive profile operations performed in accordance with an embodimentof the invention to generate composite cognitive insights. In thisembodiment, composite cognitive persona and profile operations are begunin step 1302, followed by a cognitive application requesting anApplication Programming Interface (API) key from a cognitive platform,described in greater detail herein, in step 1304. The method by whichthe API key is requested, generated and provided to the cognitiveapplication is a matter of design choice. A cognitive session token isthen issued to the cognitive application, which uses it in step 1306 toestablish a composite cognitive insight session.

As used herein, a composite cognitive insight session broadly refers toa session with a cognitive application, described in greater detailherein, where composite cognitive insights are generated and presentedto a user. In various embodiments, the composite cognitive insightsession may also include the receipt of feedback from the user, likewisedescribed in greater detail herein. In one embodiment, the cognitivesession token is used to establish a composite cognitive insight sessionthat generates a new cognitive session graph. In another embodiment, thecognitive session token is used to establish a composite cognitiveinsight session that appends composite cognitive insights and userfeedback to an existing cognitive session graph associated with theuser.

In various embodiments, the cognitive session token enables thecognitive application to interact with a cognitive session graphassociated with the cognitive session token. In these embodiments, thecomposite cognitive insight session is perpetuated. For example, a givencomposite cognitive insight session may last months or even years. Incertain embodiments, the cognitive session token expires after apredetermined period of time. In these embodiments, the cognitivesession token is no longer valid once the predetermined period of timeexpires. The method by which the period of time is determined, andmonitored, is a matter of design choice.

Direct and indirect user input data, as described in greater detailherein, is received in step 1308, followed by a determination being madein step 1310 whether or not the user is identified. As an example, theidentity of the user may be determined from the direct and indirect userinput data received in step 1308. If it is determined in step 1310 thatthe user has been identified, then a determination is made in step 1312whether a relevant cognitive profile exists for the user. If not, or ifthe user was not identified in step 1310, then a relevant cognitiveprofile is selected for the user in step 1316. Otherwise, a relevantcognitive profile is retrieved for the user in step 1314.

Thereafter, or once a relevant cognitive persona has been selected forthe user in step 1316, the direct and indirect user input data is usedwith the selected cognitive persona or retrieved cognitive profile togenerate and present contextually-relevant composite cognitive insightsto the user in step 1318. In various embodiments, composite cognitiveinsights presented to the user are stored in the cognitive session graphassociated with the cognitive session token. A determination is thenmade in step 1320 whether a cognitive profile is currently in use. If sothen it is updated, as described in greater detail herein, in step 1322.Thereafter, or if it is determined in step 1320 that a cognitive profileis not currently in use, a determination is then made in step 1324whether to convert the cognitive persona currently in use to a cognitiveprofile. If so, then the cognitive persona currently in use is convertedto a cognitive profile in step 1326. The method by which the cognitivepersona is converted to a cognitive profile is a matter of designchoice.

However, if it was determined in step 1324 to not convert the cognitivepersona currently in use to a cognitive profile, or once it has beenconverted in step 1326, a determination is then made in step 1328whether feedback has been received from the user. If not, then adetermination is made in step 1340 whether to end composite cognitiveinsights and feedback operations. If not, then a determination is madein step 1342 whether the cognitive session token for the target sessionhas expired. If not, then the process is continued, proceeding with step1310. Otherwise, the process is continued, proceeding with step 1304.However, if it is determined in step 1324 not to end composite cognitiveinsights and feedback operations, then composite cognitive insights andfeedback operations are ended in step 1344.

However, if it was determined in step 1328 that feedback was receivedfrom the user, then the cognitive application provides the feedback, asdescribed in greater detail herein, to the cognitive platform in step1330. A determination is then made in step 1332 whether to use theprovided feedback to generate contextually-relevant questions forprovision to the user. If not, then the process is continued, proceedingwith step 1340. Otherwise, the cognitive platform uses the providedfeedback in step 1334 to generate contextually-relevant questions. Then,in step 1336, the cognitive platform provides the contextually-relevantquestions, along with additional composite insights, to the cognitiveapplication. In turn, the cognitive application provides thecontextually-relevant questions and additional composite cognitiveinsights to the user in step 1334 and the process is continued,proceeding with step 1320.
